girlart33 Posted December 5, 2013 Share Posted December 5, 2013 My sister recently found this object in a creek bed in the Santiam Pass area of Oregon. (Western foothills of the Cascade range, just East of Salem). It measures aprox. 5.5 inches in length. We are wondering if it could be a Hadrosaur egg. Any other possibilties......thoughts? Thanks!

rejd Posted December 6, 2013 Share Posted December 6, 2013 Although it looks like an egg, the outer "shell" is way too thick. This is a concretion and this type of rock has fooled many a person including myself. http://en.wikipedia.org/wiki/Concretion 1 A fossil hunter needs sharp eyes and a keen search image, a mental template that subconsciously evaluates everything he sees in his search for telltale clues. -Richard E.

snolly50 Posted December 6, 2013 Share Posted December 6, 2013 rejd is certainly correct in opining that your piece has the appearance of a concretion. The size is also smaller than the typical Hadrosaur egg. Here is a close photo of a Hadrosaur egg. This is the appearance of the eggs commonly seen that originate in China. Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See Link to comment Share on other sites More sharing options...

Fossildude19 Posted December 6, 2013 Share Posted December 6, 2013 Concretions sometimes form around organic or biologic remains. There is a slight chance that there is a fossil within the concretion. Were it mine, I might use the Freeze/Thaw method to try to open it.

jpc Posted December 6, 2013 Share Posted December 6, 2013 Also dinosaur eggshell has a certain pattern in cross section. Generally there are crystal patterns that go perpendicular to the surface. yours has no such pattern. I agree with the others... nice concretion.

Grymmwulf Posted December 7, 2013 Share Posted December 7, 2013 I'd just call it a hardboiled egg. Link to comment Share on other sites More sharing options...
